Questions and Answers for OOK 20 lb. 1/2 in. Steel Mirror Support Hangers (2-Pack)

A:  I used hollow wall drive anchors.

A:  I would not recommend it. Use larger hangers that are rated for higher lb's. The problem with doing it the way you are saying is that it is unlikely that every hanger you place will be perfectly level creating more weight on one hanger than another. Also, its kind of a pain to but 6 of these in the wall when you could use 2-3 of another product.
